How do melanocytes and keratinocytes work together to protect the skin from UV?

Melanocytes and keratinocytes collaborate to protect the skin from UV radiation. Melanocytes produce melanin, a pigment that absorbs and dissipates UV rays, reducing DNA damage in skin cells. Once melanin is produced, it is transferred to keratinocytes, which are the primary cells in the outer layer of the skin. This melanin forms a protective barrier, shielding the underlying tissues from harmful UV exposure while also contributing to skin color.
